sing-disc swing check valve features
the structure length is short, its structure length is only 1/4~1/8 of the traditional flange check valve
small size, light weight, its weight is only 1/4~1/20 of the traditional flange check valve
the valve disc closes quickly and the water hammer pressure is small
both horizontal and vertical pipes can be used, easy to install
smooth flow channel, fluid resistance is small
sensitive action and good sealing performance
short disctravel, low valve closing impact
the overall structureis simple and compact, beautiful appearance
long service lifetime and high reliability

the structure length is smallthe gate valve can only be fully opened and fully closed, and cannot be adjusted or throttledaccording to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenancethe space required for installation is large
water hammer phenomenon is not easy to producethe gate has a rigid gate and an elastic gatecom/watch?v=ai-lt1dy2su

disadvantages
the overall dimensions and opening height are largethe reason is the long shutdown time
large height and long opening and closing timethe movement direction of the gate plate is perpendicular to the direction of the fluidthe use of ptfe packing is reliable and easy to operate
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches
the structure is compact, the valve has good rigidity, the channel is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, and the service life is longstandards: en 593, api609, api6d,
more video of gate valve, please see: https://wwwthe gate valve is sealed by the contact of the valve seat and the gate plateusually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1cr13, stl6, stainless steel, etc
the medium can flow in any direction on both sides, easy to install
less effort when opening and closingIndia
